Spatially resolved surface photometry at center of M31. 2. Color-magnitude array at edge of M31 central bulge. 3. Spatially resolved surface photometry at center of M32. 4. Color-magnitude array, not far from the center of M32. 5. Detection of stars that contribute the UV light. 6. Counting of Pop II red giants against the background of Pop I light in M31 central bulge, similarly in M32. 7. High-resolution imaging of dust and young stars at the centers of NGC 185 and 205, and old stars in these and NGC 147. 8. Simultaneous PC imaging of M31 globular clusters, the outer- bulge population of M31 and M32, the halo population of M31, and the outer population of NGC 185, 205, and 147. ------------------------------------------------------------------------------------ 8.
